291 Union St, San Francisco, CA 94133

The Martin 2007 Trust-owned duplex at 291 Union Street in Telegraph Hill is a three-story multi-family residential building constructed in 1900. The property has a documented history of maintenance focused primarily on roofing and deck-related improvements.

Most recently, in May 2022, a reroofing project was filed, following a consistent pattern of roofing work that has occurred approximately every three years dating back to 1990 when the first re-roofing permit was issued. The building has also undergone significant deck maintenance, with completed work in 1993 involving the replacement of a portion of the second-floor rear deck, and an earlier repair to rotted railings and waterproof deck surface in 1995, though this permit has since expired and its work status is unclear.

Additional historical maintenance records from 1987 indicate replacement of rotted materials, suggesting ongoing structural upkeep. More recently, an informational planning record was closed regarding height limits and lot average considerations for a potential horizontal addition in the rear yard, though this appears to be regulatory in nature with no immediate impact on the building's current status.
